regulator: fixed: dt: support for input supply

2012-07-05T12:49:35+00:00

Add support for input supply in DT parsing of node.
The input supply will be provided by the property
"vin-supply" in the regulator node.

regulator: fixed: Use core GPIO enable support

2012-07-03T19:29:28+00:00

This is essentially the code that was factored out into the core when the
feature was implemented.

regulator: fixed: support deferred probe for DT GPIOs

2012-07-01T18:12:59+00:00

of_get_named_gpio() needs the driver hosting the GPIO that the DT
property references to have been probed. Detect this specific failure,
and defer the probe of the whole regulator until this API can complete.

regulator: fixed: Use of_match_ptr() for of_match_table entry

2012-06-03T12:25:05+00:00

Use the new of_match_ptr() macro for the of_match_table
pointer entry to avoid having to #define match NULL.

2012-05-07T11:31:05+00:00

fixed regulator.

regulator: Remove unneeded include of linux/delay.h from regulator drivers

2012-04-23T12:20:26+00:00

All the drivers that need delay for the regulator voltage output voltage to
stabilize after being enabled or after being set to a new value has been
converted to implement enable_time and set_voltage_time_sel callbacks.
Then regulator core will take care of the necessary delay.

For the drivers that don't need the delay, don't need to include linux/delay.h.
This patch removes the unneeded include of linux/delay.h in regulator drivers.

regulator: core: Use a struct to pass in regulator runtime configuration

2012-04-09T11:37:09+00:00

Rather than adding new arguments to regulator_register() every time we
want to add a new bit of dynamic information at runtime change the function
to take these via a struct. By doing this we avoid needing to do further
changes like the recent addition of device tree support which required each
regulator driver to be updated to take an additional parameter.

The regulator_desc which should (mostly) be static data is still passed
separately as most drivers are able to configure this statically at build
time.

regulator: fixed: Support for open drain gpio pin

2012-04-02T22:17:53+00:00

Adding flag on fixed regulator board configuration structure
to specify whether gpio is open drain type or not.
Passing this information to gpio library when requesting
gpio so that gpio driver can set the pin state accordingly,
for open drain type:
- Pin can be set HIGH as setting as input, PULL UP on
  pin make this as HIGH.
- Pin can be set LOW as setting it as output and drive to LOW.

The non-open drain pin can be  set HIGH/LOW by setting it to
output and driving it to HIGH/LOW.

regulator: fixed: Don't supply voltage change ops when no GPIO is given

2012-04-01T10:59:26+00:00

Rather than replicating the core support for always on regulators use
a different set of ops with none of the enable related operations provided
when we don't have any ops. This ensures that we automatically pick up
any enhanced support for such regulators that the core has such as the
warnings about regulation constraints that can't be used.
